The cube will move 6 or so more times and then move to some lake (maybe loot lake?) and then should “turn on”. Turning on might refer to it initially spawning but I’d hope its more interesting than that.

According to YouTuber Drift0r, large purple Runes are spawning on the inside of the Cube. It’s possible that these will be left on the ground if the Cube were to move. These are the Runes which are seen on the outside of the Cube and on-screen when a player nears the Cube. It is unknown if there is any meaning behind them or if they are simply for visual appeal.
